Earthing CAT6 SWA cable connecting EVSE.

Sparkingchip

Armoured External Cat6 UTP Solid Cable (Price Per Metre) | Cat6 Cable (cablemonkey.co.uk)

When running CAT6 SWA to Electric Vehicle Supply Equipment to provide an internet connect to allow the equipment to be activated remotely using an App or by the electric supplier if the consumer has signed up for a tariff that allows the electric supplier to select the precise charging times should the SWA armour always be earthed at one end only or should it mirror the connection of the CPC or armour of the EVSE supply circuit?

    I was actually thinking of this armoured and shielded CAT6 cable

    Cat6 FTP SWA 20m Cable (cablemonkey.co.uk)

    The only time I have run CAT6 SWA was to a set of electric gates on the end of a long driveway, the groundworkers dug the trench then I ran the power SWA into IP rated double socket in a meter box built into the back of the wall by the gate along with the CAT6 SWA which I ran from a galvanised KO box inside the house earthed with a brass gland, with an ordinary CAT 6 from there to by the front door leaving the electric gate guy and the satellite TV guy who was doing all the networking in the house to finish it all off.

    I doubt I am going to be able to duck out of completing everything in the future, leaving things to others to finish off.

    From an EMC point of view, the shielding improves things as it's a lower impedance than the armour, and provides almost 100 % "coverage" of the signal conductors ... but the same rules go for the shielding as the earthing/bonding of the SWA. Certainly, never earth the shielding at both ends unless you earth the SWA at both ends.

    Whether it's best to have screened data cable, or unscreened, depends on how noisy the environment is for radiated disturbances that might affect the cable.
